NTRK1 and Familial prostate cancer: Comprehensive genomic and transcriptomic profiling revealed activation of receptor tyrosine kinase (RTK)‐mediated oncogenic (RAS/ERK and PI3K/AKT) signalling pathways, coupled with inactivation of tumour suppressors such as the lipid phosphatase PTEN and the RAS/ERK pathway inhibitor Sprouty2 (SPRY2), in advanced prostate cancer (Taylor et al, 2010).
